Abstract: A new symmetrical trisubstituted derivative of αcyclodextrin(α-CD), 6A,6C,6Etri-S-2-pyridyl-2A,2B,2C,2D,2E, 2F,3A,3B,3C,3D,3E,3F,6B,6D,6Fpentadeca-O-methyl-α-cyclodextrin, was synthesized by the reaction of trimesylated derivatives of α-cyclodextrin with 2-mercaptopyridine at the presence of K2CO3 in N,Ndimethylformamide(DMF). The compound was characterized by 1H, 2D COSY, 2D HSQC, dept135° and dept90° 13C NMR spectroscopy and electrospray ionization mass spectroscopy.
